  "message": "ThinLTO: import the functions passed to __enzyme_* calls\n\nSince #3211 a ThinLTO build differentiates in each post-link backend, which\nonly sees its own module plus what the thin link imported into it. The\nimporter follows call edges, so a function only passed to __enzyme_autodiff\nstayed a declaration there (\"failed to find fn to differentiate\").\n\nAt ThinLTO pre-link, add an internal anchor whose function_entry_count lists\nthe GUIDs of those functions and of the declarations the module\u0027s own\ndifferentiated functions call. The module summary turns them into critical\ncall edges, which the importer follows with a raised size threshold. At\npost-link, before simplification, drop the anchor and give the imported\n(available_externally) functions internal copies, so their bodies survive\nEliminateAvailableExternally until Enzyme runs.\n\nFunctions further down the call graph are still subject to the importer\u0027s\nsize limit, and noinline functions are never imported; the README says so.\n\nAssisted-by: Claude Code (Opus 5.5)\n",
